Related Art

Application scenarios of future wireless communication systems arebecoming increasingly diversified, and different application scenarioshave different performance demands on systems. In order to meetdifferent performance requirements of various application scenarios, the3^(rd) Generation Partner Project (3GPP) Radio Access Network (RAN) #72plenary decided to conduct the study of New Radio (NR), or what iscalled fifth Generation (5G). The work Item (WI) of NR was approved atthe 3GPP RAN #75 plenary to standardize the NR.

In response to rapidly growing Vehicle-to-Everything (V2X) traffic, 3GPPhas started standards setting and research work under the framework ofNR. Currently, 3GPP has completed planning work targeting 5G V2Xrequirements and has included these requirements into standard TS22.886,where 3GPP identifies and defines 4 major Use Case Groups, coveringcases of Vehicles Platooning, supporting Extended Sensors, AdvancedDriving and Remote Driving. At 3GPPRAN #80 Plenary, the technical StudyItem (SI) of NR V2X has already started.

SUMMARY

When frequency spectrum resources are shared by a V2X system and acellular system, the V2X system will have no access to resources in thecellular networks configured for downlink transmission. Inventors findthrough researches that the size of time-domain resources available forV2X transmission is variable since configurations of transmissionformats of different sub-frames or slots may vary a lot in the cellularsystem, which may lead to a disagreement between both sides ofcommunications on the determination of Transport Block Size (TB S) inmultiple transmissions. Given that the missed detection rate mayincrease sharply due to the influence of half-duplex in the V2X system,the seriousness of the above problem will be more apparent.

The second communication device 450 comprises a controller/processor459, a memory 460, a data source 467, a transmitting processor 468, areceiving processor 456, a multi-antenna transmitting processor 457, amulti-antenna receiving processor 458, a transmitter/receiver 454 and anantenna 452.

In a transmission from the first communication device 410 to the secondcommunication device 450, at the first communication device 410, ahigher layer packet from a core network is provided to thecontroller/processor 475. The controller/processor 475 implements thefunctionality of the L2 layer. In downlink (DL) transmission, thecontroller/processor 475 provides header compression, encryption, packetsegmentation and reordering, and multiplexing between a logical channeland a transport channel, and radio resource allocation of the secondcommunication device 450 based on various priorities. Thecontroller/processor 475 is also in charge of HARQ operation, aretransmission of a lost packet and a signaling to the secondcommunication device 450. The transmitting processor 416 and themulti-antenna transmitting processor 471 perform various signalprocessing functions used for the L1 layer (i.e., PHY). The transmittingprocessor 416 performs coding and interleaving so as to ensure a ForwardError Correction (FEC) at the second communication device 450 side andconstellation mapping corresponding to each modulation scheme (i.e.,BPSK, QPSK, M-PSK, and M-QAM, etc.). The multi-antenna transmittingprocessor 471 performs digital spatial precoding, which includesprecoding based on codebook and precoding based on non-codebook, andbeamforming processing on encoded and modulated signals to generate oneor more parallel streams. The transmitting processor 416 then maps eachparallel stream into a subcarrier. The mapped symbols are multiplexedwith a reference signal (i.e., pilot frequency) in time domain and/orfrequency domain, and then they are assembled through Inverse FastFourier Transform (IFFT) to generate a physical channel carryingtime-domain multicarrier symbol streams. After that the multi-antennatransmitting processor 471 performs transmission analogprecoding/beamforming on the time-domain multicarrier symbol streams.Each transmitter 418 converts a baseband multicarrier symbol streamprovided by the multi-antenna transmitting processor 471 into a radiofrequency (RF) stream, which is later provided to different antennas420.

In a transmission from the first communication device 410 to the secondcommunication device 450, at the second communication device 450, eachreceiver 454 receives a signal via a corresponding antenna 452. Eachreceiver 454 recovers information modulated to the RF carrier, andconverts the radio frequency stream into a baseband multicarrier symbolstream to be provided to the receiving processor 456. The receivingprocessor 456 and the multi-antenna receiving processor 458 performsignal processing functions of the L1 layer. The multi-antenna receivingprocessor 458 performs reception analog precoding/beamforming on abaseband multicarrier symbol stream provided by the receiver 454. Thereceiving processor 456 converts the processed baseband multicarriersymbol stream from time domain into frequency domain using FFT. Infrequency domain, a physical layer data signal and a reference signalare de-multiplexed by the receiving processor 456, wherein the referencesignal is used for channel estimation, while the data signal issubjected to multi-antenna detection in the multi-antenna receivingprocessor 458 to recover any second communication device 450-targetedparallel stream. Symbols on each parallel stream are demodulated andrecovered in the receiving processor 456 to generate a soft decision.Then the receiving processor 456 decodes and de-interleaves the softdecision to recover the higher-layer data and control signal transmittedby the first communication device 410 on the physical channel. Next, thehigher-layer data and control signal are provided to thecontroller/processor 459. The controller/processor 459 performsfunctions of the L2 layer. The controller/processor 459 can beassociated with a memory 460 that stores program code and data. Thememory 460 can be called a computer readable medium. In DL transmission,the controller/processor 459 provides demultiplexing between a transportchannel and a logical channel, packet reassembling, decrypting, headerdecompression and control signal processing so as to recover ahigher-layer packet from the core network. The higher-layer packet islater provided to all protocol layers above the L2 layer, or variouscontrol signals can be provided to the L3 layer for processing. Thecontroller/processor 459 is also in charge of performing error detectionusing ACK and/or NACK protocols to support HARQ operation.

In a transmission from the second communication device 450 to the firstcommunication device 410, at the second communication device 450, thedata source 467 is configured to provide a higher-layer packet to thecontroller/processor 459. The data source 467 represents all protocollayers above the L2 layer. Similar to a transmitting function of thefirst communication device 410 described in the DL transmission, thecontroller/processor 459 performs header compression, encryption, packetsegmentation and reordering, and multiplexing between a logical channeland a transport channel based on radio resource allocation of the firstcommunication device 410 so as to provide the L2 layer functions usedfor the user plane and the control plane. The controller/processor 459is also responsible for HARQ operation, a retransmission of a lostpacket, and a signaling to the first communication device 410. Thetransmitting processor 468 performs modulation and mapping, as well aschannel coding, and the multi-antenna transmitting processor 457performs digital multi-antenna spatial precoding, including precodingbased on codebook and precoding based on non-codebook, and beamforming.The transmitting processor 468 then modulates generated parallel streamsinto multicarrier/single-carrier symbol streams. The modulated symbolstreams, after being subjected to analog precoding/beamforming in themulti-antenna transmitting processor 457, are provided from thetransmitter 454 to each antenna 452. Each transmitter 454 first convertsa baseband symbol stream provided by the multi-antenna transmittingprocessor 457 into a radio frequency symbol stream, and then providesthe radio frequency symbol stream to the antenna 452.

In a transmission from the second communication device 450 to the firstcommunication device 410, the function of the first communication device410 is similar to the receiving function of the second communicationdevice 450 described in the transmission from the first communicationdevice 410 to the second communication device 450. Each receiver 418receives a radio frequency signal via a corresponding antenna 420,converts the received radio frequency signal into a baseband signal, andprovides the baseband signal to the multi-antenna receiving processor472 and the receiving processor 470. The receiving processor 470 and themulti-antenna receiving processor 472 jointly provide functions of theL1 layer. The controller/processor 475 provides functions of the L2layer. The controller/processor 475 can be associated with the memory476 that stores program code and data. The memory 476 can be called acomputer readable medium. The controller/processor 475 providesde-multiplexing between a transport channel and a logical channel,packet reassembling, decrypting, header decompression, control signalprocessing so as to recover a higher-layer packet from the secondcommunication device 450. The higher-layer packet coming from thecontroller/processor 475 may be provided to the core network.
